3D Files and Modifications

The parts were designed in Autodesk Fusion 360. If you're interested in modifying the parts, you can download the source file. If you're using different 3D modeling software, you can save it out as a STEP, IGS, OBJ and other file formats. The STLs can be downloaded "as is" from the repo sites listed below.

Slice Settings

Download the STL file and import it into your 3D printing slicing software. You'll need to adjust your settings accordingly if you're using material different than PLA.

  • 230C Extruder Temp
  • No heated bed (65C for heated)
  • 90% Extrusion Multiplier
  • .6mm Nozzle
  • 0.72 Extrusion Width
  • .4mm Layer Height
  • 20% infill
  • 4 to 6 skirt outlines (brim)
  • Custom Supports

Check if you have enough Filament 


We recommend using a brand new spool of filament as it will require over 400 grams of filament to complete. You can check if you have enough filament to complete the print by weighting the spool of filament before starting the print. A 1kg spool (2.2lbs) usually weights about 321g.



Fitting the helm


Although the source files are available to cut up into smaller pieces, we designed the parts to fit on larger printers with minimal supports. 


We recommend using a printer with at least a 300x300x300 size bed. To fit the helm on our bed, we rotated the model 45 degrees and then centered it in the middle of the bed.




Adding Supports


The star gems on the sides of the helm sit above the base of the helm, so we'll need to add a small amount of supports to hold up these parts.


To optimize supports, we used Simplify3D custom supports with the pillar resolution set to 16mm and placed them around the star. We made sure to give a bit a spacing away from the sides of the helm. 


Preventing Strikes


Strikes occur when the hot end becomes misaligned from hitting parts of the model that have warped. The lower "horns" on the side of the helm have a tendency to cause strikes, so we can add one support pillar on each horn to prevent them from wrapping. 

Printing the Gems


The six gems on the front of the helm are printed in blue  translucent PLA, while the two star gems on the sides are printed in a red translucent PLA. 


The blue gems are able to print without any supports. They will however need a brim to hold the parts as it prints.


The red gems print as is with the top facing down on the bed.


Mirror Gem


The blue gems on the left side of the helm will need to be mirrored to fit the right side of the helm. We can use the mirror feature under: mesh > mirror mesh > mirror Y.
